Because, my fellow writers, they are going to have to do just that before the end of the book and we as the authors will have to decide under what circumstances they would be willing to do/say/think what they never thought they would. Don’t we have the best jobs?!! 🙂
One of my favorite instances of this is in a *terrible* movie, Catwoman, with Halle Berry. Her friends have given her this totally wild and sexy leather outfit as a gift telling her it’s for when she’s having a dating emergency. She says it’s lovely, but she’ll never wear it. Oh yeah? Guess what she reaches for the first time she goes out embracing her new life. Wearing the outfit shows her – and us – how much she has changed.
So…. what would your characters never do? Now go make them do it!
